SPECIFICATION forming part of Letters Patent No. 254,070, dated February21, 1882,

I Application filed May 20, 1881. (Model) To all whom it may concern Beit known that I, FRED TERSTEGEN, a citizen of the United States,residing at Elizabeth, in the county of Union and State of New Jersey,have invented new and useful Improvements in Nose-Pieces for Eyeglasses,of which the following is a specification.

The object of my invention is, first, to adapt the nose-pieces'ofeyeglasses to be adjustedo quicklyand accuratelyto the required positionout of the plane of the glasses; second, to arrange them to be held inthe position to which they are set 5 third, to make them self closing orfolding; and, lastly, to construct them so I 5 that they will not catchin the guard, clothing,

or other object.

In the accompanying drawings, Figure 1 represents'in elevation myimprovement in nosepieces applied to an eyeglass. Fig. 2 shows the samewith the and guard attachment. Fig. 3 is an edge view of Fig. 1. Fig. 4.is a sectional View of Fig. 2, taken on line 00 ac. Fig. 5 is amodification of Fig. 1. Fig. 6 represents the improvement adaptedspecially for application to frameless glasses. Fig. 7 shows anose-piece capable of adjustment in different directions. Fig.8 shows anedge elevation of Fig. 6. Fig. 9 represents a self-opening nosepiece.Figs. 10 and 10 show the nose-piece represented in Fig. 7 arranged toopen automatically.

Referring to the drawings, A represents the lenses, B the bow-sprin g,and D the nose-pieces.

In Figs. 1 and 2 the bow-spring and nose- 3 5 piece are represented asformed in one piece,

thebend which connects them forming a spring, a. The nose-piece may,however, be made separate and connected at its attached end by a spiralor other suitable spring with the bowspring or with the frame, or, if aframeless glass is used, with a clamp on the edge of the lens. Thepurpose of the spring is to make the nose-pieces self-closing.

To hold the nose-pieces in place when set out of the plane of theglasses, any suitable device maybe employed. In Fig. 1 a finger lug orstop, I), is shown forthis purpose. This finger lug or stop consists ofan angular piece of metal attached to the nose-piece so that its freeend pro- 50 jects out at right angles to the nose-piece. In-

stead of connecting the lug finger or stop I) with the spring throws thenose-piece back in place, as indicated by the dotted lines.

The sliding-link connection for the nose-rest may be made in variousways. Forexainple,

the nose-piece, it may be attached to the bowspring or to the frame offramed glasses, or to aclamp placed on the lens of frameless glasses,

in the same manner as it is attached to the nose-piece. The said stop,when attached to the nose-pieces, as in the figure, is passed by thebow-spring when the'nose-pieces are moved out to the side oppositethatit occupies when the nose-pieces are closed, and, engaging the edge ofthebow-sprin g, prevents the nose-pieces from springing back. Whenattached to thebow-spring, frame, or lens the nose-piece is moved pastthe end of the stop. The said stop may also he adjustably attached toits place of 6 5 attachment, so as to be capable of movement toward andfrom the axis of the nose-piece, and thus enable the nose-piece to beset and held at variable angles to the plane of the glasses.

In Fig. 2 the device for holding the nosepiece in position also servesas a guard for the end of the nose=piece, which prevents the lattcr fromcatching in objects. It consists of a slotted link, E, pivotallyattached at one end to the bow-spring; or it may be attached to theframe or to the lens, if preferred. The said link is connected with thenose-piece bya pin,

d, passed through the slot and fixed t0 the nosepiece. The edge of theslot in the link may be provided with one or more notches, 0, adapted toreceive and retain the pin d, and thereby hold the nose-piece out of theplane of the glasses, as shown in Fig. 4. When the pin is released fromthe notch thespring-connection throws the nose-piece back in line withthe lenses.

Fig. 5 shows a modification of Fig. 1. In this the nose-piece isseparate and pivoted to the bow-spring, frame, or lens, as the case maybe. A flat spring, D, is also attached to the bow-spring B or to thelens or to the frame, so that its free end, in which there is a notch,f,is opposite the pivoted end of the nose-piece. When the latter is turnedout its end bears against and forces back the spring until its 5 angularportion enters the notch f, where it is held, and thereby the nose-pieceis held in position. As soon as released from the notch it may bepivoted to the nose-piece, and its slotted and notched part connectedwith a pin entered into the bow-spring, the frame, or a clamp attachedto the lens, and instead of a sliding link an extension link may beemployed, made in two or more parts, arranged to slide together when thenose-piece is folded in and to extend when the nose-piece is moved outof the plane of the glasses. The link connection has, in addition toregulating the opening of the nose-piece, the further advantage ofpreventing the nose-pieces from catching in objects and being broken, asfrequently occurs when the ends swing free.

In Fig. 6 the nose-piece has one end provided with a claw, g, whichgrasps the edge of the lens (or the frame, if used,) and the other endpivoted to a link, which in turn is pivoted or fastened to theattachment which connects the bow-spring with the glass; or it may beattached directly to the bow-sprin g or to the frame. The nose-piece,when closed or folded, is parallel to the lens, but by pushing its clawend in line with the edge of the lens the swinging end of the nosepieceis forced out at an angle to the plane of the glasses, as shown. Thefixed end of the link may be doubled over and fastened by the pivotwhich attaches the link, and thereby form a spring-loop, h, whichpresses against the bearing of the link and tightens the latter on itsbearings, so that it will stay in the place it is set. This mode oftightening the nose-piece and holding it in place may be applied tothosenose-pieces which have one end free, instead of the spiral springnow employed, as shown in my Letters Patent No. 238,985, dated March 15,1881.

Instead of a spring-loop for retaining the nose-piece (shown in Fig. 6)in position, the edge of the lens may be prgyjdpfiith 1 1 otches, asindicated by the dotted lines, to receive and retain the claw g,andthereby hold the nosepiece out in the required position.

In Fig.7 the nose-piece, which may be square or of other suitable shape,is held on a pivot, i, fixed to one end of a link, the opposite end ofwhich is pivoted or otherwise suitably attached either to the end of thebow-spring, to the frame, or to a clam p on the ed go of a framelessglass. A suitable spring may be attached to the link, so as to throw itaround at right angles to the plane of the glasses, and thereby retainthe nose-piece out of the. plane. By pivoting the nose-piece to the linkits surfaces will adjust themselves axially to the part of the nose thenose-piece bears against.

In Fig. 9 the nose-piece is attached in a pondent position to one end ofa link, the opposite end whereof may be connected by a pivot or othersuitable device with the attachment that connects the bow-spring withthe frame or lens, or in any other convenient and suitable manner. ,Aspring, I, engages the end of the link and retains it at nearly rightangles to the glasses and the nose-piece in asuitable position out ofthe plane of the glasses, as shown.

The link which supports the nose-piece in Fig. 7 may be provided with aspring, I, similar to that shown in Fig. 9, to hold the nose piece inposition, as shown in Figs. 10 and 10, and the said nose-piece may beconnected with the lens, or with the bow-spring or frame, if preferred,at its lower end, as indicated by the dotted lines in Fig. 7. Thelinkmay,however, be held in position by a sprin g-bearin g similar to thatshown at h in Fig. 6, or of any other suitable construction.

The nose-pieces shown in Figs. 7, 9, 10, and 10 are folded by turningthe link on its pivot to a position about parallel to the plane of thelenses, as indicated by the dotted lines in Fig. 10.

The essential features of my invention are embraced in the constructionillustrated by Figs.

2 and 4.; and they consist, first, in adapting the nose-pieces to beinstantly set and secured in the required position out of the plane ofthe glasses; second, in connecti-ngboth ends of the nose-pieces with theglasses 5 and, third, in providing springs for throwing the nose-piecesinto position, either to fold them or to open them. The first of theseessentials is provided by the notched link E, which limits the movementof the nose-piece, so thatwhenit is moved the required distance it isinstantly engaged by the notch and thereby adjusted for placing on thenose, instead of having to he put on and taken off to find the rightposition. Modifications of this arrangement are shown by the step b,Figs. 1 and 3, and the notched springf, Fig. 5. In Figs. 9 and 10 thedevice for retaining the nose-pieces in position consists of the springI, a yielding stop or adjustment being employed because the nose-piecesare designed to be self-opening.

The secondessential feature of my inventionviz., the connecting of bothends of the nose-piece with the frames, Sac-which in Fig. 2 isaccomplished by the spring a and slotted link E is omitted from Figs. 1,3, 5, 9, 10, and 10, but is shown in modification in Figs. 6 and 7.

The third essential feature, consisting in the spring connection forthrowing the nose-pieces into position, is shown by the spring a inFigs. 1 and 2, and a modification is shown in Fig. 5 but this device isomitted from Figs. 6, 7, and S. In the case of the arrangements ofnose-pieces shown in Figs. 9, 10, and 10,

the spring is applied to retain the nose-pieces out of the plane of theglasses instead of in a folded position, as in the arrangementsheretofore described, thereby illustrating how the invention may beadapted to retain the nosepieces in either a closed or open position, asmay be desired.

The nose-piece shown in Fig. 7, it will be observed, has no device forretaining it in place or throwing it into position; but the arrangementshown in Figs. 10 and 10illustrates how it may be arranged when suchattachments are required. This figure,however, shows anosepiece which isadapted to turn on its longitudinal axis, and thereby when applied tothe nose to adjust itself to the surface against which it bears.
